No. The spray solution has been found to be extremely safe and poses no danger to animals or humans. The active ingredient is a natural essential oil that has been used in human, animal, and environmental applications for thousands of years. Although it can cause discomfort in certain individuals with allergies to citronella, it is considered safe for the vast majority of people and animals.

This would be highly unlikely. The citronella solution is buffered to minimize any discomfort should it get into the eyes. However, as with any aerosol product, the spray should not be aimed directly into the eyes.

It will effectively deter low to moderately agitated dogs without increasing aggression. Other personal defence products such as pepper spray and mace have been proven to increase aggressive behaviour in dogs. A second notable advantage over other spray deterrent products is the absence of harmful blow-back that can incapacitate the user and make the user even more vulnerable.

SprayShield is designed to be used by kennel employees, animal control officers, utility workers, meter readers, delivery personnel, joggers, bicyclists, outdoor enthusiasts, sportsmen, or anyone who may potentially come in contact with a moderately aggressive dog.

SprayShield has shown to be extremely effective in deterring low to medium level aggression. In many cases dogs that are strongly motivated to attack cannot be stopped without restraint. The best protection is to be aware of the presence of and avoid an encounter with a potentially dangerous dog.
